WILLIAM P. ALLEN, OF CHICAGO, ILLINOIS.

SYRINGE.

SPECIFICATION formingpart of Letters Patent No. 657,328, dated September 4, 1900.

Application filed March 8, 1899.

To all whom it may concern.-

Be it known that 1, WILLIAM P. ALLEN, of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Vaginal Syringes, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to a douche or syringe for cleansing the vagina and parts connected therewith, and particularly to means for holding the syringe securely in place uponthe person.

' plishing this without permitting the leakage of the washing or medicated liquid upon the garments on or around the patient, while leaving the patientfree to change position and move about within reasonable limits.

Many vaginal syringes which were intended to be held in position by hand have heretofore been constructed; but it is a physical impossibility for most if not all patients to hold a syringe in place with sufficient pressure to prevent leakage for a sufficient length of time to effect the desired treatment. Other syringes have been designed to be held in place by the pressure of the patients body upon them; but both of the constructions above referred to havethe great disadvantage of compelling the patient to remain constantly in one position throughout the treatment. My invention avoids all these objections and provides mechanical means for holding the syringe in position tight enough to prevent leakage without confining the patients hands in any way and without limiting other movements of the body within reasonable limits.

My invention alsoconsists in the details of construction of the syringe and the means for holding it in place hereinafter described and claimed.

In the drawings, Figure 1 is a sectional side View, Fig. 2 a side view, Fig. 3 a plan, and

Serial No. 708,231. (No model.)

Fig. 4 a bottom view, o'f'my improved syringe.

' Fig. 5 is a side, and Fig. 6 a perspective, view of the complete apparatus ready for use.

In the drawings similar letters represent .similar parts throughout the several views.

A is an imperforate conical top of the syringe, shaped substantially as shown.

B is the base of the syringe, adapted to be attached to the top A by the screw-threads a. This base B is preferably made approxi- 'mately cylindrical and of the meanidiametor-i. e., half the larger diameter-of the cone, so as to afiord a brace to the cone at about the middle of its inclined sides.

0 is a removable tube adapted to fit in a socket b in the top A and socket c in the base 13 and form a continuous pipe from the inlet D in base B to the series of holes E in the top A. Around the topA are cut the large slotted holes F, leading into the chamber d, between the walls of A and B and the tube 0, having the outlet pipe G.

forms an air-space H H, which helps to cool the portion of the top A which is below the screw-thread a, and makes its temperature lower than the part above, which is in contact. with the. hot water inside the syringe.

' Around the base B is sprung a bar I. For

lightness this is made preferably of wire, as shown; but it maybe made solid and of any suitable material. This bar extends on each side of the'syringe, forming arms, substantially as shown in the drawings; but the length may be varied within reasonable limits without departing from my invention. This bar also has the additional function of resting against the lower edge of the conical top and supporting and stiifening it. The arms formed by the ends of the bar maybe made with and a part of some part of the syringe without departing from my invention.

Pivotally secured to ends K K of the bar I is a strap J, adapted to pass up over the shoulder of the patient. The upper portion of this strap might be divided so as to pass departing from myinventionr over each shoulder; or two straps mightbe I find that inv general an-inelastic strap gives thegbest results, as the body of the patient; gives as much springas'isnecessarygbut an elastic strap may be used, if desired, without The inlet-pipe D of the'syringe is connected by a flexible tube M to the bag or otherres ervoir N containing thefhot' wateir or medi-i 1 cated liquid.

In. practice find that without the bar it is practicallyimpossi-ble-to putsu fficient tension on the strap to hold the syringe as required, while with the bar as shown the result is obtained; with a very' light pressu reand without any inconvenience ttothe patient. If an additional pressureis desired, the patient may easily obtain it by v ina waste-receptacle, and: by manipulating the valves P and P the liquid in receptacle slightly elevating the shoulder over which: thestrap passes. The end of 'tubeOis placed N is passed through t-ubesM and-G andlholes E into the vagina, expanding it until all folds and. creases are filled and 'cleansed with: the liquid; In cases of prolapsusof thewomb the pressure of the water is alsoused to force it-back to its normal position. 1 After performing these cleansing and medicati ng f ,funetions theliquid passesthrou-gh the slots Fin-to the chamber at. and out through the waste-pipe 0. By raising or lowering the bag Njl e pressure of the liquid may be regulated as desired to eflect the results above referredto, .Jllhe. medicated liquidmay also be forced through the syringe by any of the *common formsof force-pumps.
